Hi,

I'm trying to use J-Scope, but as soon as a click 'start' I get the message 'Failed to initialize HSS'.
I've used J-Scope in the recent past on the same host and target successfully, and debugging using MCUXpresso and the J-Link still works fine.
I'm not aware that I changed anything that might break J-Scope's functioning and the error message doesn't provide a clue unfortunately.

How can I get J-Scope working again?

J-Link software 749d
macOS 14.1.2 (Apple M1)
LPC844M201

Thanks in advance.

Kind regards,

Remco Poelstra

Hi,

I'm sorry about the confusion. I meant V794d.
I just tried V794e and it shows the same problem.
Before trying V794d I was using V792c, and I downloaded V794d in the hope it was already fixed.
I've tried V788h as well, as it was still on my system. It fails as well.
On Win11, V788m gave the exact same error message. I don't know if it ever worked on Win11 for me, I've never used it there.
Given the fact that I've used JScope successfully a few months ago, I would come to believe that the probe's firmware is at fault and not the JScope application. But this is just a feeling. I don't know which FW version was on the probe in the past.

Please let me know if there is anything I can test for you.
